ABSTRACT:

Background: Skeleton is an excellent investigating material in living and non-living population for genetic, anthropological and forensic purposes. Anatomical knowledge of human osteology, in the evaluation of death may help to shed light on legal issues such as sex and age determination, parentage and racial identity.  With racial differences,  it’s difficult to implement a uniform method for determining sex. Therefore, the need for present study  was felt. Many bones of skeleton present size related sexual differences, those of the pelvis usually displayed differences in morphology independent of size as the sex hormones influence the reproductive functions. In the present study an attempt has been made study to arrive at appropriate metric data, regarding sex determination of North Indian pelves using indices calculated upon dry hip bones, sacrum & pelvis as a whole.

Materials and Methods: The study was conducted on 50 adult pelvis (M: F= 40:10) obtained from Government Medical College, Amritsar. Measurements related to Pelvic Brim Index, Coxal Index, Index I & Index II of Greater Sciatic Notch, Ischiopubic Index, Sacral index, Longitudinal Curvature index & Corporobasal index were taken by standardized methods, indices were calculated & results were statistically analyzed.

Results: Amongst the various indices calculated in present study Coxal Index, Index I & Index II of Greater Sciatic Notch, Ischiopubic Index & Sacral index were found to be significantly sexually dimorphic.

Conclusions: Since skeletal characteristics vary among populations; therefore the present study provides a database for various significant pelvis related indices amongst North Indian population to optimize the accuracy of sex identification.

Key words: Sexual dimorphism, Forensic, Anthropologists, Orthopaedicians, Hip bone, Pelvis, Sacrum, Index.
